«Облачные» технологии не смогут решить проблемы без Вашего участия20 июня 2013 Безусловно можно выделить много заманчивых плюсов в использовании «облачных» технологий как инструмента для хранения и работы с Большими Данными. И тем не менее, на данном этапе развития у «облачных» систем пока еще есть недостатки, связанные с безопасностью хранения и управления ценной информацией. Что это за угрозы и как их избежать, читайте на нашем сайте. (Материал опубликован на английском языке)
Cloud may help clear up some of the costlier and thornier problems of attempting to manage Big Data environments, but it also creates some new issues. As Ron Exler of Saugatuck Technology recently pointed out in a new report, cloud-based solutions “can be quickly configured to address some big data business needs, enabling outsourcing and potentially faster implementations.” However, he adds, employing the cloud also brings some risks as well.
Data security is one major risk area, and I could write many posts on this. But management issues also present other challenges. Too many organizations see cloud as an cure-all for their application and data management ills, but broken processes are never fixed when new technology is applied to them. There are also plenty of risks with the misappropriation of big data, and the cloud won’t make these risks go away. Exler lists some of the risks that stem from over-reliance on cloud technology, from the late delivery of business reports to the delivery of incorrect business information, resulting in decisions based on incorrect source data. Sound familiar? The gremlins that have haunted data analytic and management for years simply won’t disappear behind a cloud.
Exler makes three recommendations for moving big data into cloud environments – note that the solutions he proposes have nothing to do with technology, and everything to do with management:
- Analyze the growth trajectory of your data and your business. Typically, organizations will have a lot of different moving parts and interfaces. And, as the business grows and changes, it will be constantly adding new data sources. As Exler notes, “processing integration or hand off points in such piecemeal approaches represent high risk to data in the chain of possession – from collection points to raw data to data edits to data combination to data warehouse to analytics engine to viewing applications on multiple platforms.” Business growth and future requirements should be analyzed and modeled to make sure cloud engagements will be able “to provide adequate system performance, availability, and scalability to account for the projected business expansion,” he states.
- Address data quality issues as close to the source as possible. Because both cloud and big data environments have so many moving parts, “finding the source of a data problem can be a significant challenge,” Exler warns. “Finding problems upstream in the data flow prevent time-consuming and expensive reprocessing that could be needed should errors be discovered downstream.” Such quality issues have a substantial business cost as well. When data errors are found, it becomes “an expensive company-wide fire drill to correct the data,” he says.
- Build your project management, teamwork and communication skills. Because big data and cloud projects involve so many people and components from across the enterprise, requiring coordination and interaction between various specialists, subject matter experts, vendors, and outsourcing partners. “This coordination is not simple,” Exler warns. “Each group involved likely has different sets of terminology, work habits, communications methods, and documentation standards. Each group also has different priorities; oftentimes such new projects are delegated to lower priority for supporting groups.” Project managers must be leaders and understand the value of open and regular communications.
